I've sent a save the date out to a ton of friends...I grew up going to a holiday party every year for my parents friends and their kids, and wanted to start the tradition for my group of friends.
I don't want to be slaving over the stove for a week beforehand, so what are your best "make ahead' recipes? There will be lots of adults and kids, mix and mingle party so no formal dinner. It starts at 4 PM and goes on throughout the evening to give people an opportunity to drop in.
Go!
